I love this sooooooooo~ much! I always loved them. They're so cute. ^~^ you know there's actually ALOT of couples in transformers? I never knew they had that much! There's actually a website that has all(or almost) the couples(or moments) on it. It was a long list... Though, they'll be always be my favorite.

XDD actually she's not a human! She's an alien. But no, in the series there only a few robot/humanoid couples. They're very rare X3 There is the episode "Sea Change" in which Seaspray falls in love with Alana, and there is the episode "The Girl Who Loved Powerglide" in which the human Astoria falls in love with Powerglide. But as far as I know those are the only canon ones :3

Optimus already has a transformer girlfriend XDDD ~~ He has Elita-1.

(well, actually, in the Marvel comics, there are two sort of "implied" couples: Skids & Charlene, and Skullgrin & Ethel)
